Abstract

A method, system, and computer program product for identifying network congestion in a communication system. A connection manager identifies a number of packet delay times of a plurality of data packets within the communication system; determines whether the at least one packet delay time meets a threshold; and responsive to the at least one packet delay time meeting the threshold, adjusts a congestion indicator.

What is claimed is: 
     
       1. A method of determining connection quality in a communication system, the method comprising:
 measuring a plurality of packet delay times associated with a plurality of data packets within the communication system; and 
 determining the connection quality based on the plurality of packet delay times; 
 wherein the step of determining the connection quality comprises: 
 determining whether each of a number of consecutive packet delay times of the plurality of packet delay times is less than a second threshold; and wherein the method further comprises adjusting a congestion indicator to inactive if each of the number of consecutive packet delay times of the plurality of packet delay times is less than the second threshold. 
 
     
     
       2. The method of  claim 1 , wherein the step of determining the connection quality comprises:
 determining whether any of the plurality of packet delay times is greater than a first threshold; and the method further comprises adjusting a congestion indicator to active if any of the plurality of packet delay times is greater than the first threshold. 
 
     
     
       3. The method of  claim 1 , wherein the plurality of packet delay times each comprise a difference in time between two packets being sent from a user equipment in the communication system. 
     
     
       4. The method of  claim 1 , wherein the plurality of packet delay times each comprise a difference in time between two packets being received from a base station in the communication system. 
     
     
       5. The method of  claim 1 , wherein the plurality of packet delay times each comprise a difference in time between one packet being received from an application layer and being sent to a base station of the communication system. 
     
     
       6. The method of  claim 1 , further comprising:
 reporting the connection quality to an application layer of a user equipment. 
 
     
     
       7. A system for determining connection quality in a communication system, the system comprising:
 means for measuring a plurality of packet delay times associated with a plurality of data packets within the communication system; and 
 means for determining the connection quality based on the plurality of packet delay time; 
 wherein the means for determining the connection quality comprises determines whether each of a number of consecutive packet delay times of the plurality of packet delay times is less than a second threshold; and wherein the system further comprises means for adjusting a congestion indicator to inactive if each of the number of consecutive packet delay times of the plurality of packet delay times is less than the second threshold. 
 
     
     
       8. The system of  claim 7 , wherein the means for determining the connection quality determines whether any of the plurality of packet delay times is greater than a first threshold; and the system further comprises means for adjusting a congestion indicator to active if any of the plurality of packet delay times is greater than the first threshold. 
     
     
       9. The system of  claim 7 , wherein the plurality of packet delay times each comprise a difference in time between two packets being sent from a user equipment in the communication system. 
     
     
       10. The system of  claim 7 , wherein the plurality of packet delay times each comprise a difference in time between two packets being received from a base station in the communication system. 
     
     
       11. The system of  claim 7 , wherein the plurality of packet delay times each comprise a difference in time between one packet being received from an application layer and being sent to a base station of the communication system. 
     
     
       12. The system of  claim 7 , further comprising:
 means for reporting the connection quality to an application layer of a user equipment. 
 
     
     
       13. A computer program product comprising logic encoded on a non-transitory computer-readable tangible media for determining connection quality in a communication system, the logic comprising instructions for:
 measuring a plurality of packet delay times associated with a plurality of data packets within the communication system; and 
 determining the connection quality based on the plurality of packet delay time; 
 wherein the instructions for determining the connection quality comprise instructions for: 
 determining whether each of a number of consecutive packet delay times of the plurality packet delay times is less than a second threshold; and wherein the computer program product further comprises instructions for adjusting a congestion indicator to inactive if each of the number of consecutive packet delay times of the plurality of packet delay times is less than the second threshold. 
 
     
     
       14. The computer program product of  claim 13 , wherein the instructions for determining the connection quality comprise instructions for:
 determining whether any of the plurality of packet delay times is greater than a first threshold; and the computer program product further comprises instructions for adjusting a congestion indicator to active if any of the plurality of packet delay times is greater than the first threshold. 
 
     
     
       15. The computer program product of  claim 13 , wherein the plurality of packet delay times each comprise a difference in time between two packets being sent from a user equipment in the communication system. 
     
     
       16. The computer program product of  claim 13 , wherein the plurality of packet delay times each comprise a difference in time between two packets being received from a base station in the communication system. 
     
     
       17. The computer program product of  claim 13 , wherein the plurality of packet delay times each comprise a difference in time between one packet being received from an application layer and being sent to a base station of the communication system. 
     
     
       18. The computer program product of  claim 13 , further comprising instructions for:
